The program itself reduces the problem to canonical form, and produce its graphics solution, the graph displaying direct restrictions, the area of solutions and the direction vector. The decision gives a very clear and understandable. You can disable / enable the display on the chart some elements of solutions, for example - grid or shading SDT well, etc. You can also scale the graph, making the study of solving the problem is even more intuitive and user-friendly.

After solving the problem, you can see and explore relevant theory that is built into the program itself! One need only click the "theory".
